TOGGLE BOLT Filed April 10, 1936 Patented Oct. 27, 1936 UNITED STATESPATENT OFFICE TOGGLE BOLT Walter E. Snyder, Troy, N. Y.

Application April 10, 1936, Serial No. 73,751

1 Claim.

The present invention relates to new and useful improvements in boltsand has for its primary object to provide, in a manner as hereinafterset forth, a bolt including novel means for anchoring said bolt in awall, partition or other structure.

Other objects of the invention are to provide an anchor bolt of theaforementioned character which will be comparatively simple inconstruction, strong, durable, highly efiicient and reliable in use andwhich may be manufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become ap- 5 parent from a study of the followingspecification, taken in connection with the accompanying drawing whereinlike characters of reference designate corresponding parts throughoutthe several views, and wherein:

Figure 1 is a view of the invention, showing the same being insertedthrough an opening which has been prepared therefor in a wall orpartition.

Figure 2 is a view, showing the invention after it has been inserted.

Figure 3 is a view in side elevation of the l anchor.

Referring now to the drawing in detail, it will be seen that thereference numeral I designates a threaded bolt having a slotted head 2on one end for receiving a screw driver. The reference numeral 3designates a partition or wall in which an opening 4 has been formed forthe reception of the bolt I.

Threadedly mounted on the bolt l is a nut 5 or the like from the innerend or face of which integral lugs 6 project. It will be noted that thelugs 6 parallel the bolt I on opposite sides thereof. Riveted to thelugs B are resilient, di-

verging anchoring legs 1 which terminate, at their free ends, inoutturned feet 8.

It is thought that the operation of the invention will be readilyapparent from a consideration of the foregoing. The bolt I, with the nut5 5 threaded thereon, is inserted through the opening 4 in the wall orpartition 3, the resilient anchoring legs I being forced inwardly duringthis operation, as illustrated to advantage in Figure 1 of the drawing.However, as soon as the 10 resilient legs I clear or pass the opening 4in the wall or partition 3, said legs spring outwardly to the positionbest seen in Figure 2 of the drawing for engagement with the wall orpartition 3 in a manner to prevent the bolt from being with- 15 drawn.The projecting lugs 6 greatly facilitate riveting the resilientanchoring legs I to the nut 5 as it would obviously be a comparativelydifiicult operation to secure said legs directly to the body of said nut5.

It is believed that the many advantages of an anchor bolt constructed inaccordance with the present invention will be readily understood, andalthough a preferred embodiment of the device is as illustrated anddescribed, it is to be understood 25 that changes in the details ofconstruction and in the combination and arrangement of parts may beresorted to which will fall within the scope of the invention asclaimed.

What is claimed is:-

A device of the class described comprising a bolt including a slottedhead on one end, a nut threadedly mounted on the other end portion ofsaid bolt, integral lugsprojecting from the inner end of the nut andparalleling the bolt on opposite 35 sides thereof, and resilient,diverging anchoring legs rigidly secured to the lugs.
